Osprey .300 Remington Short Action Ultra Magnum and 7mm Rem. Ultra Magnum Arbor Sleeve for the .223 Laser Bore Sight Cartridge

The Osprey International 300RSUM Remington Short Action Ultra Magnum Arbor accepts the Osprey Bore Sight .223 Laser Diode Module. Simply insert the module into the arbor and then insert the arbor into the chamber. A bright laser beam shines through the bore of the gun and is visible on the target, allowing for initial sighting in of optical sights. This system saves time and money that would otherwise be wasted getting the shots on paper.
